Dear experts:
I am trying to run a tutorial recommended. https://mne.tools/dev/auto_tutorials/preprocessing/plot_20_rejecting_bad_data.html#rejecting-epochs-based-on-channel-amplitude

My data is not from the tutorial. It is an EEG. Also I have this outputs. Of course I use evoked = epochs.average() and it says less than one epoch. What can I do?

You can look at `epochs.drop_log` or `epochs.plot_drop_log` to see why. See
for example:

https://mne.tools/dev/auto_tutorials/epochs/plot_10_epochs_overview.html#creating-epoched-data-from-a-raw-object

yes I did (epochs.plot_drop_log) but I just see a lot of columns with 100%. From where I deduce all channels are dropped. I don?t know what explanation for that.

I just saw that you can do epochs out of raw, events, and tmin tax
